Publication number: 20240012177Abstract: Meta-surface devices may be advantageously used for miniaturization, planar and thin film, high spatial resolution, and dense integration into optical devices. They have the potential to be used for steering a beam propagation direction, shaping wave-front light, and imparting information for application such as sensing, imaging, light detection, and ranging. However, meta-surface devices may have poor overall efficiency when compared with traditional optical devices. Embodiments of this disclosure relate to meta-surface devices including a pattern of high-index pillars with a low-index coating. Advantageously, the low-index coating may improve optical efficiency of the meta-surface devices which may make these meta-surface devices suitable for a variety of applications.Type: ApplicationFiled: January 5, 2022Publication date: January 11, 2024Applicant: Metalenz, Inc.Inventors: Seyedali Forouzmand, Pawel Latawiec
